In recent years, with the superior product performance, the  Moisture Analyzer  has been accepted by more and more people. The moisture meter can be used to complete the measurement in a few minutes, especially in the fields of grain, meat and seeds. And in the laboratories and production of agriculture, forestry, rubber and other industries. In use, the use environment has a significant impact on the efficiency of the moisture meter, and the most suitable use environment should meet the following points: 1. The use of  Halogen Heating Moisture Analyzer  should not be installed in places with direct sunlight and high air humidity, and the indoor temperature should be higher than 5-40 °C. 2. The environment of the moisture meter should be avoided in the room with corrosive gas to prevent corrosion of the circuit and affect the service life of the equipment. 3, there are requirements for the power supply, should be avoided in the place where the power supply is unstab...

In order to ensure the stability and accuracy of the  Moisture Analyzer , we need to calibrate the equipment regularly. Today, let's take a look at the calibration specifications of the moisture analyzer. When calibrating the moisture analyzer, the glass fiber paper was placed on a moisture analyzer sample pan and prebaked at 105 ° C for 10 minutes. Turn off the heating device, adjust the weight on the measuring device, return the indicator of the moisture analyzer to zero, and record the weight value R on the weighing pan at this time.Remove the  5kg Calibration Weights  on the measuring device, and measure 5 ml of sodium chloride solution with a 5 ml pipette, and evenly drop it on the glass fiber paper, and turn on the measuring device. After balancing, write down the scale line at this time. The value and the weight value on the weighing pan. Turn off the measuring device, turn on the heating device, and warm up to 105 °C. After 1 hour, the measuring device is turned ...

In general, the  Moisture Analyzer  measures a typical sample in a few minutes, the detection result is accurate, and the detection efficiency is much higher than the oven method, avoiding the error caused by the artificial factor to the measurement result. In addition, the moisture meter has the advantages of wide moisture range, high precision, clear display, rapid measurement, stable performance, reliable index, etc. It can be carried on site for rapid detection. In the actual use of the moisture meter, various problems will be encountered, as the user should learn how to handle it correctly. Common problems include: 1. After the instrument is turned on, the display remains black: no voltage; the power cord is not connected; the fuse is blown; the instrument is damaged. 2. The measurement time is too long: The measurement mode selected in the operation is not suitable. It is recommended to try to replace a suitable operation mode. 3. Cannot be heated after starting...

The  Moisture Analyzer  is an instrument for rapid determination of the moisture of the substance. The moisture meter consists of a heating system and a weighing system. The operation is relatively strong and not very complicated, but it also has very strict safety requirements. The online moisture meter is capable of detecting the moisture content of various organic and inorganic solids, liquids, gases and other samples. It is called a moisture analyzer. According to the measurement principle, physical measurement and chemical measurement can be classified into two categories. If there is a problem in the use of the  Halogen Moisture Analyser , the operator can refer to the following measures for treatment. The quality of the treatment will directly affect the use of the later equipment, and will also affect the effective service life of the equipment. 1. Pre-titration of fresh anolyte, drift too high: 1) There is residual water in the titration system, and the molecula...

Moisture Analyzer  is the general name of all instruments for measuring moisture content. It is mainly used to measure the moisture content in solid, liquid and slurry materials. According to different test principles, we can divide it into many kinds, among which the most common ones include halogen moisture meter. , Karl Fischer moisture meter and online moisture meter, these different moisture meters have their own advantages, and their application range is not the same. 1. Halogen moisture meter: Halogen moisture meter, as a new type of fast moisture detecting instrument, the halogen moisture meter is heated by a circular halogen lamp and intelligently operated. It can quickly and evenly dry the sample to obtain accurate moisture measurement results. The clear moisture measurement information display enables intuitive, simple and convenient instrument operation. The halogen moisture meter is suitable for moisture detection of samples such as solids, granules, powders, gels, ...

Electronic Balances  are precision electronic instruments that are susceptible to external environmental factors, so we need to find out the source of these errors so that we can reduce the error to get more accurate results. Let's briefly analyze the source of the error of the electronic balance. First of all, it is necessary to select a room with dustproof, shockproof, moisture proof and temperature fluctuation prevention as the balance room. The balance with higher accuracy should also be used in the constant temperature room. Secondly, the balance should be placed on a firm and reliable workbench and placed in an appropriate position for easy operation. Before the balance is installed, check whether the components are complete and intact according to the balance list of the balance; carefully clean all parts of the balance. When installing, refer to the balance's instructions, properly assemble the balance, and adjust the level. After installation, check the installation...

The acidity meter is abbreviated as  PH Meter  and consists of two parts: the electrode and the main unit. If the electrode can be properly maintained during use, the standard buffer is prepared as required, and the electric meter is properly operated, the pH indication error can be greatly reduced, thereby improving the reliability of chemical experiments and medical test data. First, the correct use and maintenance of the  Precision PH Meter   electrode 1. When the composite electrode is not used, it can be fully immersed in 3M potassium chloride solution. Do not dip with washing liquid or other water-absorbing reagents. 2. Check the bulb at the front end of the glass electrode before use. Under normal conditions, the electrode should be transparent without cracks; the bulb should be filled with solution and no bubbles should be present. 3. When measuring a solution with a large concentration, shorten the measurement time as much as possible, and carefully...

The  CO2 Incubator  is a commonly used incubator for biological experiments. Therefore, different experiments have different requirements for the incubator. The Chinese chemical instrument network  Incubator Supplier  will take stock of the reasons forthe carbon dioxide incubator. The carbon dioxide incubator uses two different carbon dioxide maintenance systems. One way is to mix carbon dioxide and air in a certain ratio and then blow it into the incubator by using an air pump. Another way is to turn on the carbon dioxide valve to charge carbon dioxide when an automatic carbon dioxide detection control system is detected that detects a lower concentration of carbon dioxide than the desired concentration. Since the former method consumes carbon dioxide and it is not easy to accurately control the concentration of carbon dioxide, the advanced carbon dioxide incubator uses an automatic monitoring system to maintain the concentration of carbon dioxide. Carbon dioxi...

(1) Wear white gloves when operating the  Analytical Balance . When picking up the scaled object and adding or subtracting the weight, the lift hub must be closed, otherwise the beam or the lifting lug will be displaced or even dropped, and the knife edge and the knife bearing will be damaged; the switch lifting hub should be light. (2) The scaled object shall not be placed directly on the balance pan, and the weighing bottle or weighing paper load shall be applied. (3) When weighing moisture-absorbing or volatile articles, the weighing cap must be tightly closed and the weighing operation should be carried out as soon as possible. (4) Items that are too cold or too hot cannot be weighed on the balance. They should be cooled in the desiccator to room temperature and weighed. (5) The object and weight should be placed in the middle of the plate. W&J  is specialized in   produce  Analytical Density Scale ， Our products are very popular , if you are inter...
